CONVERTIBLE CHAIR BED.

Application filed April 12, 1927. Serial No. 183,088.

My invention relates to a chair of the type adapted for conversion, byextension of certain parts, to form a bed. i

The principal object of my invention is to provide such a convertiblechair which is adapted to be over-stuffed and upholstered to resemblethe ordinary typeof over-stuffed arm chair in present day use. A secondobj ect is to provide means for converting such a chair into either areclining chair or a bed. A still further object is to preserve thecomfort and appearance of the ordinary arm chair, without interferingwith its ready conversion into a comfortable bed. Such an article can bemade to match other pieces'of furniture to form a drawing roomset, andcan be ordinarily used in the drawing room as a chair. It is of such asize that it can beeasily moved from one room to another, when its useas a bed is desired.

Other objects and advantages of the invention will be apparent from thefollowing specification, which should be read with the understandingthat the form, construction, and arrangement of the several parts may bevaried, within the limits of the claims hereto appended, withoutdeparting fromv the pirit of the-invention as set forth in said arms.

Fig. 8 is a sectional detail, showing the folding of the foot extensionon the seat frame.

In the drawings, the reference numeral 1 designates the frame of theseat and base portions of my chair, said frame being preferably made ofwood and similar in form and construction to that of the'usualover-stuffed chair, as shown in Figs. land 2. 2 designates, in general,the upholstery, any well known type and. form, and which'is, in general,attached to the frame 1 inthe usual manner. 3 and 8 are the arms,whiohare also framed and upholstered in the usual manner, except that one orboth of said arins is mounted upon hinges and adapted to swing outwardlyand downwardly in aman'ner to be described later. i

A pair of baranembers 4, preferably angle iron, Fig. 8, are the seatportion ofthe frame 1, Figs. 2 and 8, one at each side thereof, at thebase of the arms 3 and3. A second pair of bar members 5 are 'pivotallyconnected at 5 Figs. 2 and 8, with the forward ends of the fixed barmembers 4, and are adapted either to be fold.- ed back bars 4, as shownin Fig. 8, or to be extended permanently mounted uponparallel andadjacent to said-fixed which ma be of forwardly in line therewith, asshown in Fig. I

2. The are rigidly joined by a cross/member 6, to which a pair of legs 7are pivotally connected. As shown in Fig. 7'said legs are pivoted to thecross bar 6 at 8, and either folded against said cross bar or extendeddownwardly to form legs or supports therefor, as indicated in dottedlines. When so extended, said legsare slightly inclined outwardly, toprovidegreater lateral stability, and are provided with shoulders 9which engage fixed pins 10. both .to limit their swinga the pivots 8 ofa Theifolding bars 5 and the end cross member 6 constitute an extensionframe, which, when extended with its free end supported by the legs 7,forms as shown in Figs. 1 and 2,.a horizontal continuation of the seatframe are adapted to be forward ends of the folding bars 5 bars 4. Asuitable resilient fabric, such as the tinuous, with its forward endconnected with the cross member 6, and being adapted to fold back uponitself when the extension frame 5-6 is folded back upon the seat frame,as seen in Fig. 8.

A rear extension frame is formed similarly to the forward extensionframe 5-6, having side bars 12 pivoted at 13, Fig. 2 to the rear ends ofthe fixed bars 4 and a rear cross member 14. This rear extension frameis adapted to swing back horizontally, as shown by the dotted lines inFig. 2, to form a rearward continuation of the seat frame, and theresilient fabric is continued to its rear cross member 14 as indicated.Thus when the two end frame portions are extended, as shown in Fig. 2,theyform with the fixed center portion virtually a single frame ofsuitable length to make a bed, and actually support a continuous resilient bed fabric, upon which a suitable mattress, not shown, may beplaced.

The rear extension frame 12-14, when swung to a substantially uprightposition, as shown in Fig. 2, forms the support for the back 15 of thechair, and when lowered to its extended or horizontal position, saidback 15 is adapted to be inverted to form a leg or support for saidframe, Fig. 2. The back 15 is formed in the usual manner over a woodenor other suitable rigid frame 16, similar in general form to the usualchair back frame, except that it is provided with grooves 17 2 and 5, inits rear surface into which the extension frame 12 14 can fit. connectedat 19 with the extension frame members 12 and at 20 with the sidemembers of the back frame 16, and are so positioned that the back 15 canbe inverted and swung over the end of the extension frame 12-14, as seenin Fig. 2. When the latter is in its horizontal position, as shown insaid Fig. 2, the top of the back 15 rests upon the floor, and said backis tilted under the frame 1214 sufiiciently to cause the end member 14of the latter to bind securely against said back when weight is applied.This binding prevents the end of the frame 12-14 from dropping, and alsoprevents the back 15 from slipping out of its supporting position.

In the chair position, as shown in Figs. 2 and 5, the extension frame1214 lies entirely within the grooves 17 at the back 15. The back orbottom of said extension frame is covered with a piece 21 of the covermaterial of the chair, which conceals it from view. Said cover piece Iis preferably continuous from the rear bottom of the chair, as inFig. 2,its upper end being secured to the extension cross member 14 by beingpassed around and under a strip 22 suitably secured thereto. The back 15and extension frame 12 14 are held in the chair position by suitablelatches,

preferably swinging notched. members 23,

Fig. 6, pivoted at 24 to the frame members 12, and adapted to engagepins 25 in the rear ends Links 18 are pivotally of the arms 3 and 3'.Suitable retarding springs are provided to partially support the weightof the back 15 and extension frame 1214, so that they will not dropsuddenly when the latch-es 23 are released. I prefer to make suchsprings as flat leaves 26, Fig. 6, having their lower ends secured at 27to the base frame 1, and their other ends bearing against the sidemembers 12 of the extension frame.

When the device is in the extended or bed position, the arm 3 can beswung outwardly and downwardly, out of the way, as indicated in dottedlines in Fig. 1, to provide more convenient access to the bed. For thispurpose I connect said arm 3 with the base frame 1 by hinges 28. A bolt29, Fig. 4, slidable through the side of the base frame 1, and adaptedto enter a socket 30 in the arm 3, holds said arm in its upper position.The lower end of said bolt is provided with a handle 31 by which it maybe operated, and it is also provided with a pin 32 travelingin a bayonetslot 33 to hold it in its upper position. The joint between the chairbase and the arm 3 is concealed by the continuous outer covering 34.Both arms may, of course, be made to swing if desired. The flat surfaces35, Fig. 1, when the arm is lowered, can be used as a convenientbed-side stand.

I prefer to provide the seat portion of my chair with additional helicalcompression springs 36, Figs. 2'and 8, of the usual type, under the wirefabric 11. Such springs reinforce the wire fabric at the regionreceiving the greatest weight, both as a chair and as a bed, that is,the seat of the chair and the central portion of the bed. The forwardedge of the chair seat is also preferably reinforced by a transverseflexible or articulated wire 37, independent of the wire fabric 11 andconnected with, the side frame members 4 by tension springs 38, Fig. 3.The covering 39 of the front of the chair base is continued up and overthe front edge of the seat, to conceal the fold of the wire fabric 11,and is provided with a welt 40 to serve as a further reinforcement ofsaid front edge, Fig. 8. The end of said covering 39 is secured to theextension frame members 5 by suitable resilient connections, such asstrips 41 of elastic material, as shown in Fig. 3, so that the frontedge of the seat may give without straining said covering. The endofsaid covering is also slit, as shown at 42, Fig. 3, and the edges of theslit are joined by an elastic connecting strip 43, for the same purpose.

I provide a removable seat cushion 44, Fig. 1, made in two parts foldedtogether along one end, as shown at 45. Both parts are preferablyprovided with springs, not shown, after the manner of the well knownspring-filled cushions. When the forward extension frame 4-4 isextended, the cushion 44 can be opened out and laid upon the seat andsaid extension, covering both, and providinga full cushioned recliningor extension chair.

The front and rear of' the base frame 1 are cut away at their upperedges, as shown in front at 47, Fig. 1, to provide clearance for thedeflection of the wire fabric 11. The front cut out portion alsoprovides clearance for the deflection of the forward edge of the seatwhen used as a chair.

It will be seen that my device, when in its chair position, has both thecomfort and appearance of the ordinary over-stuffed arm chair, theentire extension mechanism being concealed. To make a reclining chair,the

cushion 44 is removed, the forward extension frame 45 is swung forwardlyand its legs 7 extended to rest upon the floor, and said cushion isopened out and replaced. To make a bed, the back and rear extensionframe 1214 are let down, said back is swung over the end of said frameto rest upon the floor, the arm 3 is let down, and a suitable mattress,not shown, is placed upon the wire fabric 11. A chair of ordinary sizewill provide a bed inches wide by six feet or more in length, dependingupon the height of the chair back. I
